which is made straight, a little lower than the cutting-teeth (J D, projects forward so as to have both edges inclined, and has a cavity formed in front of its base, giving the cuttingteeth 0 D the appearance of being formed upon the rear edge of the clearing-teeth B.

The teeth 0 are beveled upon the right-hand side, and the teeth D upon the left-hand side from the base to the points, and the points of the said teeth (ID are rounded off and sharpened, as shown in Fig. 1.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- A saw provided with three teeth in each set, the front one being abase recessed clearer in line with the saw-plate, and the other two being cutters vertical on one edge,-inclined on the other, and sharpened as well as rounded on the points, as shown and described.
